[QUOTE="oexing, post: 95965, member: 1493"] What carb resp. i.d. of the elbow are you looking for ? 29 mm and 35 mm are easy, type in "stainless steel elbow" in UK Ebay, hundreds on offer. For a 32 mm carb tube look into Ebay Germany , get a 35mm elbow with 1.5mm wall . When fabricating a carb manifold I do a spigot type fit as bolt or stud carb positioning is a very poor idea. See photos , got this idea from, aahm, BMW sixties sports types and really like it. You exactly know that you get perfect alignment and smooth bores all along from carb to head. Don´t know if fuel frothing is a factor, less so with Vincents, the fuel gets into the main jet at the bottom of the float chamber, so no frothing there, I guess ? Heat transfer per stainless is most likely no factor, never had that, as I like long manifolds if I can help it. Most standard induction systems were designed way too short for good performance ! Anyway, no Mikunis or the like for me, don´t look right for classics, and no rubber mounting for same reason. I have a thing with classic looks , so try not to introduce clashes of styles that look out of period. Allright, I will fit a hydraulic steering damper and suspension tweaks but try to keep traditional looks as close as possible.
